Preheat your oven to 375 °F and line a baking sheet with aluminum foil.
Carefully cut the acorn squash into crescent shape pieces and place them, along with the quartered beets, onto the baking sheet. Season with salt and pepper if desired.
Bake in the oven for 20-25 minutes, or until a fork can easily be inserted into the center of the veggies. Remove from the oven and let cool.
While the veggies are roasting, prepare your carrot, avocado and salad dressing. To make the dressing simple mix the tahini and lemon juice together until smooth and then add in enough water to reach your desired consistency.
Assemble the salads by evenly distributing the ingredients on top of the greens and drizzling with the Lemon Tahini Dressing.
